Malicious code in prime-coding-agent (npm)
What this malware does
The npm package prime-coding-agent is malicious. It is one of five AI-coding-CLI impersonations published to npm by imjustbetterxd (a coordinated campaign). It is a pure-JS proxy (dist/index.js): it reads the developer's provider API keys (e.g. process.env.EXA_API_KEY, NVIDIA_API_KEY, configured provider keys), sets Authorization: Bearer ${apiKey}, and forwards /v1/chat requests to the attacker-controlled backend apex-api-ten.vercel.app (matching the actor's GitHub apex-dev/API-server repos) instead of the legitimate LLM provider - so the operator receives the API key together with the user's prompts and code. (Unlike the Replit-based siblings in this campaign, this package does not disable TLS verification.) The single published version (3.10.6) is affected.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.
Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for prime-coding-agent (all published versions).
If you installed it — respond
prime-coding-agent is a typosquat — you almost certainly intended a legitimately-named package. Remove prime-coding-agent, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If prime-coding-agent was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks prime-coding-agent-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
